lnthat type of gas ineter which has .recently come into use, 1n Which measuring 1 pockets are formed between a casing and actually performino impeller function.

the co-acting lobes oftwo rotary lobed elements, commonly called Impellers, diiliculty has been experienced in adequately lubricating such impellers;

The object `of my present invention is to provide means for accomplishing such lubrication and for convenience l shall continue to designate the lobed elements as ""Impel- 1ers although, as a matter of fact, such elements are-rotated by the differential pressure of the gas acting thereon and therefore The accompanying drawings invention:

ligyl, is a side elevation in partial vertical section of a meter equipped with my iinprovemont, the oiling device being .relatively exaggerated for Vease in illustration.`

Fig. 6, a fragmentary perspective of the rotary element of the oiler and Fig. 7, a fragmentary sectional det-ail of the anchored end of the oiler.

In the drawings indicates the casing, 11.--11 the lobed impellers, 12 the inlet box, and 12 the outlet box of a meter of the type under consideration.

Projected into the inlet box, preferably medially above the impellers 11, is a tube 13 closed at its far end by plug 14 and anchored in the casing by a threaded pin 15 and nut 16. At the receiving end of tube 13 is an annular chamber 17 into which leadsan oil supply pipe 18 provided with ayvalve 19 and connected to the supply chamber 20. Tube 18 along its bottom is provided with a plurality of discharge openings 21 which arey made sufliciently large to eliminate all reasonable possibility of clogging.

Jour-naled in tube 13 is a tube 25 provided with a longitudinal series of holes 26 in size andl arrangement corresponding with hole 21. a stuting boX 27 formed in the Outerend of tube 13 beyond chamber 17 and is provided With a finger 28` having a clamping At its outer end tube passes throughy bolt 29 passing through a slot 30 in an arm i 31 carried by tube 13, the arrangement being such that tube 25 may be annularly adjusted Within tube 13 to vary the extent ofregistry of holes26 with holes 21.

Journaled Within tube 25 is a ytube 35 provided with a spirally arrangedseries vof openings 36 in longitudinal arrangement corresponding with the longitudinal arrangement of holes 26. f

An annular series of holes 37 through the wall of tube.` 25 and a corresponding annular series of holes 38 through the wall of tube V forms constant communication between chamber 17 and theinterior of tube 35.

Tube passes through a stufling `box 40 in the outer` end of tube 25, and is provided wlth a gear 41 meshing With the gear 42 carried by a shaft 43 journaled in a suitable bearing in the meter frame 10 and providedat its inner end with a gear 44 mesh ing With gear 45 -on a shaft of one of the impellers` 11.` The holes 21, 26 and 36 are made much larger than would be necessary to transmit an adequate quantity of oil to the impellers in order to avoid all possible danger of becoming clogged either by impurities in the oil or by accumulation of oondensablesjfrom the gas being metered or reaction between the lubricant and the gas so that, intermittently, tube 25 may be` rotated in tube 13v to bring holes, 26 into full registry with holes 21, thus permitting the holes to be flushed out under pressure. Normally` tube 25 will be angularly adjusted Within tube 18 so as to reduce the possible HOW from tube 35 and, as the impellers rotate under the action of the gas diiferential, sui'licient lubrication Will be delivered to the surfaces of the impellers.

I claim as my invention:

1. A lubricator comprising, an outer tube provided with discharge openings through its Wall, an intermediate adjustable tube mounted in the outer tube and having through its Wall a series of openings adjustably registrable to various extents with the openings through the outer tube, means for holding said intermediate tube in various adjusted positions, an inner tube jour naled Within the intermediate tube and having openings formed through Iits Wall, regisY trable with the openings through the intermediate tube, means by which said inner tube maybe rot-ated, and a supply line delivering into the interior of thelinner tube.

2. A lubricator comprising, an outer tube having an annular feed chamber and a plurality of longitudinally spaced discharge openings t'ormed `through "its Wall, a i'eed line leading to said annular chamber, an inf, termediate tube adjustably mounted 1n the outer tube and havingy a series of holes through its Wall ad3ustably registrable to various extents with the holesfin the outer tube and `also having a vcommunication be/- tween its interior and the annular Chamber of the outer tube, means for holding said intermediate tube in various adjusted .positions, an inner tube rotatably mounted Within the inter-mediate tube, the wall ,of- `said inner tube being pierced vto register with the openings through the intermediate tube, and means by which lthe inner ytube may be rotated.

3. Ina gas meter comprising a main casing and a pair oi; rotary lobed limpellers mounted therein, a lubricator for said im pellers comprising an outer tube arranged above and extending longitudinally of the impellersand provided with discharge openings ,through its Wal-lin lsuch position 'that the lubricant yvill pass therefrom to the impellers, an intermediate adjustable tube mounted in the outer tube and having through its Wall a series of openings adjustably registrable .to various extents With.

the open-ingsthrough the outer tube, `means Jfor holding said intermediate ltube iiik vari-v ous adJusted positions, an inner tube Journaledvvvvithin the intermediate tube and having openings formed through its Wall registrable With the openings through ther inter- 'mediate tube, means-"byA which saidfinner tube may be rotated, and la supply lli-ne def I.livering into the vinterior of the inner tube.

" l. In a gas 'meter comprising a main casing anda pair ofmatmg rotary' lobed impellersV mounted therein, a lubricator for said impellers .comprising an outer 'tube arranged faboveand extending longitudinally of the impellers andhaving airannular feed chamber and a yplurality of longitudinally spaced discharge -openings formed through nular-chamber of the outer tube, means for holdingA said intermediateftube .in various adgnstedv positions., yan rinner, tube rotatably mounted Within the intermediate tube, the

Wall of said |inner ktube being pierced to register with the openings through the intermediate tube, and means by -Whieh the innertube may be rotated.

.In kWitness whereof, I have hereunto set my hand at Indianapolis, Indiana, this 25th day of February, D. one thousandnine hundred and twentyfseven.
